Drops the custom WebRTC DataChannel pipeline + pion deps + WSS signaling
client + wire framing. Every in-browser playback now uses HLS over HTTP
from the daemon (Tailscale/LAN/UPnP). Browser P2P never re-enabled.
Wire renames (incompatible with web < 2026-05-26): agent.WebRTCSession
=> agent.StreamSession, SyncResponse.WebRTCSessions (JSON: webrtcSessions)
=> StreamSessions (JSON: streamSessions). MIN_AGENT_VERSION is bumped
to 0.9.4 on the web side so older agents see an upgrade card.
Also fixes the libx264 'VBV bitrate > level limit' abort by clamping
the encoder bitrate to the effective output height instead of the
requested label (carried over from the prior 0.9.3 unreleased work).
The seed_file vertical (mode=seed_file handler + engine.SeedFile) was
retired with the in-browser P2P player. [downloads.webrtc] config block
deleted; existing TOML files with the section still parse fine.
Extends the probe binary so it can do more than verify tracker reach:
when given a real file, it builds a single-file torrent in memory,
seeds it via the WebTorrent peer wire, and prints the magnet URI
(with the WSS tracker injected). Useful for proving the end-to-end
streaming path before any actual unarr daemon work lands.
Internally uses anacrolix/torrent's metainfo.Info.BuildFromFilePath
+ bencode.Marshal to mint InfoBytes, then AddTorrent → seed loop.
Piece length picked from a libtorrent-like ladder (16 KiB → 4 MiB)
so the resulting torrent is interoperable with mainstream clients.
Validation: synthesised a 5 s 320×240 H.264+AAC mp4 with ffmpeg
(`testsrc + sine`), seeded it via this binary against the production
wss://tracker.torrentclaw.com endpoint, opened the in-browser player
at /stream/<info_hash>. Browser reported `downloaded: 105 KB / 105 KB`
and rendered a working <video> with controls. Seeder reported
`uploaded=107452 bytes`. Pieces flowed P2P over WebRTC data channel,
zero relay through TorrentClaw infrastructure.
Closes the manual half of Fase 4.4 of the streaming plan; the
companion player change (file.blob() in place of the v2-removed
file.renderTo) is committed separately on the web side.
Tiny `go run ./cmd/wstracker-probe` that spins up an anacrolix/torrent
Client with WebRTC enabled, advertises a random info_hash to the given
WSS tracker, and reports via Callbacks.StatusUpdated whether the
announce round-trip succeeded.
Used as the production smoke for unarr ↔ wss://tracker.torrentclaw.com:
$ /tmp/wstracker-probe -tracker wss://tracker.torrentclaw.com -timeout 30s
[probe] tracker=wss://tracker.torrentclaw.com info_hash=e978df8d... timeout=30s
[probe] tracker connected: wss://tracker.torrentclaw.com
[probe] tracker announce OK: wss://tracker.torrentclaw.com ih=e978df8d...
[probe] OK — tracker announce succeeded
Disables TCP/uTP/DHT/IPv6/UPnP — only the WS tracker path matters here.
Exit codes: 0 success, 1 announce error, 2 timeout.
